Abstract: 1479734 Electro-medical apparatus C W MORLE (W L S Kloosman) 15 July 1974 [16 July 1973] 33841/73 Heading A5R An apparatus for electro-medical treatment of a patient, comprises a generator of both voltage and current pulses, the voltage pulses being variable as to frequency, pulse width, amplitude, duration of treatment and polarity, and the current pulses being variable as to frequency, pulse width and duration of treatment, electrodes connected to the generator for applying voltage pulses to the patient, and a coil connectable to the generator for applying a magnetic field corresponding to the current pulses. The frequency may be 20-2000 pulses per second, the amplitude may be 12-20 volts for the voltage pulses and 0-500 microamps for the current pulses, the pulse width may be 0.2-0.9 of the pulse period, and the pulses may be either positive or negative or alternately positive and negative. A unijunction transistor Q1 produces oscillations at a frequency determined by a resistor R1, variable by a control (17), Fig. 1 (not shown), and a capacitor 31 to which may be connected a capacitor 32 by a switch S1A (16) giving factors Xl or X10. The oscillator output is applied via an emitterfollower Q2 to transistors Q3, Q4 from which two trains of oppositely phased pulses are passed to transistors Q9, Q13 and Q10, Q14 respectively. A pair of transistors Q7, Q8 of which one is off when the other is on acts as a gate, to pass one train of pulses or the other. Transistors Q11 and Q12 are coupled respectively to Q9 and Q10, the transistors Q11-Q14 forming a bridge circuit in which either the pair Q11, Q13 or the pair Q12, Q14 is operative according to whether Q7 or Q8 is off. The voltage pulse output is taken from a set of ten potentiometers 40 (only one shown), with controls (15a - 15j), feeding ten sockets (14a - 14j). A multivibrator comprising transistors Q5, Q6 drives Q7 and Q8 so that the polarity of the output alternates when a switch 37 (19) is centralised. Other positions of switch 37 provide for positive or negative pulses respectively. A second output from transistor Q4 is applied to Q15 which feeds pulsed current to terminals 42, corresponding to a socket (12) for the magnetic field coil. The equipment includes a control (23) for timing the operation of the apparatus which is powered by a rechargeable battery. The voltage electrodes may be of nickel, or of aluminium or stainless steel foil.

Filed: 1975-08-18
Abstract: 1480865 Releasable couplings HALLIBURTON CO 18 Aug 1975 [11 Oct 1974] 34305/75 Heading F2G [Also in Division E1] A controlled release apparatus 20, e.g. for launching a cementing plug 23 in a well casing 21, which is actuated by a closure member being driven therein and a subsequent internal pressurization thereof, includes a tubular casing 30 (connected to the drill pipe 16) having an internal ledge 56, a collar 50 having a contractible external ledge 51 releasably interlocking with the ledge 56 of the casing 30, a tubular sleeve 60 within the collar 50, the sleeve holding the ledge 51 of the collar 50 in engagement with the ledge 56 of the casing 30, and an adapter 70 (which carries the cementing plug 23) attached to the collar 50, the arrangement being such that when a closure member 9 is driven through the casing 30 to engage and block the sleeve 60 and the casing 30 is subsequently pressurized, the sleeve 60 is moved so that the ledge 51 of the collar 50 can contract and release from engagement with casing 30, thereby releasing the adapter 70 (and cementing plug 23). As described the casing 30 is in two parts screwed together, the ledge being formed by the upper end of the lower part 40 and carrying a bearing race 91 and thrust bearing 92 which permits rotation of the adapter/collar assembly. The collar 50 is a double collet spring having upper fingers 51 which engage the ledge in the casing 30 and lower fingers 55 which engage a groove 77 in the adapter 70 to secure them together. The sleeve 60 has an out-turned upper end 62 which holds the fingers 51 on the casing ledge and is secured to the adapter 70 by shear pin 80. In use a closure member 9 is pumped down the drill pipe 16 until it seats against the sleeve 60 and the drill pipe 16 is pressurized. This causes a downward force on sleeve 60 which shears pin 80 and moves the sleeve 60 downwardly as shown in Fig. 2b so that the fingers 51 can disengage from the casing ledge. The sleeve 60, collar 50 and adapter 70 then move downwardly until the middle portion 53 of the collar 50 engages a shoulder 45 in the casing part 40, thus stopping the collar 50. At this position the lower fingers 55 of the collar are clear of the casing part 40 and can move outwardly from the groove 77 in adapter 70, thus completely releasing the adapter 70 as shown in Fig. 2d. The cementing plug 23 (carrying the adapter 70, sleeve 60 and closure member 9) can then move down the casing 21. The apparatus also includes a second cementing plug 24 secured to the first cementing plug 23 by shear means (not shown) and which can be released prior to the release of the first cementing plug 24 by pumping a ball 12 down the drill pipe 16, which ball 12 engages the second cementing plug 24, subsequent pressurization of the drill pipe 16 then causing the shear means between plugs 23 and 24 to break.
